With the attached portfolio's beta at 2.27%:

• How can I determine what the expected return will be after 3 - 5 years?
• Can you infer a projected rate of return (as a %), based on the portfolio beta alone? i.e. using the S&P 500's beta as the comparison.
• How do you calculate if the projected return is actually worth the risk?

I'd really appreciate help on this!
